Abstract: The present invention relates to a grouting apparatus. In detail, the present invention provides a grouting apparatus which injects a reinforcing material into an object in which an injection hole into which the reinforcing material is injected is formed, the grouting apparatus including: a pumping unit which pumps the reinforcing material to be injected into the object; an injection pipe which has one side connected to the pumping unit, and the other side inserted into the injection hole, and injects the reinforcing material conveyed by the pumping unit into the object; a vibration generating unit which generates vibration; and a vibration wire which has one end coupled to the vibration generating unit, and the other end extending along the injection pipe and coupled to a tip of the injection pipe, and transmits the vibration generated by the vibration generating unit to the injection pipe.
